Riders to Watch at the 2013 Tour of Spain

Chris Horner (RadioShack Leopard)

8 / 10

One of the sport’s most veteran riders, Horner’s 2013 has been a huge disappointment thanks to a knee injury that kept him out of the Tour of California and the Tour de France. After taking most of the spring and summer to heal, Horner seems to be on track again: He returned to racing at the Tour of Utah and briefly challenged for the overall title. That said, Horner hasn’t raced the Vuelta since 2009 and hasn’t finished the race since 2007. At one of the hardest Vueltas in years, he’ll need to be at his best. Luckily, the American rides for a strong RadioShack-Leopard team that includes Matthew Busche, Robert Kiserlovski, and Haimar Zubeldia, each of whom is capable of scoring high finishes on his own.
